JIRA Emails not getting sent

[Gurinder Summan]

Hi All

Today morning i had to manually flush around 5K notification emails and all were sent in an hour or so. The problem is i see that emails are geting queued again in the mail queue and are not getting sent automatically. (they get sent if i manually flush them)

How can i fix this problem? What can be the possible root causes for this?
